Abstract: 1,225,841. Stretching devices. DENNISON MFG. CO. Ltd. 17 April, 1968, No. 18133/68. Heading B5A. A device for stretching injection moulded fastenings, each of which consists of a filament 1, a head 2 and a bar 3, comprises a series of cross-bars 16 carried between a pair of spaced apart rotating chains (not shown). Each crossbar carries a pair of transversely slidable shoes 26 and 27 which are guided by longitudinally extending track cams and which carry normally closed jaws 36 and 37. Fixedly mounted centrally of each cross-bar is a pair of lower jaws 63, 64 adapted to co-operate with jaws 61, 62 carried by a rotating chain 51 mounted above, and intermediate the ends, of the cross-bar carrying chains. In operation, batches of fastenings interconnected by sprues 8, 9 and 10 are fed to the feed end of the cross-bar carrying chains and are engaged by jaws 36, 37 which have been temporarily cammed open by stationary cams located in advance of the chain 51. The fastenings are then fed under chain 51, where they are engaged by jaws 61 and 62, and then through a region in which the cam tracks guiding the shoes 26 and 27 are made to diverge. Each pair of jaws 36, 37 is thus moved away from its associated pair of jaws 61, 63 or 62, 64 and the filaments are stretched. Finally the stretched filaments are fed through a station at which the track cams converge and are released from the jaws by movement of chain 51 and a second temporary opening of the jaws 36, 37 by stationary cams located beyond chain 51.

A stroke adjusting motor for a hydraulic pump comprises a rod 32 the end 33 of which is subjected to pump outlet pressure. Movement is resisted by a spring 48 and assisted by a spring 28. As shown the rod 32 engages a swash-plate 58 through a cylinder 64 slidable on a sleeve 66 having a groove 70 connected to the pump outlet through a safety valve 78 which opens at maximum pressure to put the swash-plate into neutral position. The force of the springs may be adjusted by means of a plug 20 and a screwed connection 18.

Abstract: 1,229,754. Endless scraper conveyers in mines. GEWERKSCHAFT EISENHUTTE WESTFALIA. 12 Feb., 1969 [8 Nov., 1968], No. 7592/69. Heading B8A. [Also in Division E1] In an installation for driving a pipe comprising lengths 11 through the ground, spoil is removed from the interior of the pipe by a scraper chain conveyer 19, 20 having an ascending portion which terminates in a discharge station. Spoil removed from the working face by a machine 16 is discharged to a zone 18 by a tube 17. The spoil is moved from the zone by the conveyer which is supported in the pipe by rollers 21, 21<SP>1</SP>, 43 and leaves the pipe through a channel 26 having an adjustable guide roller 27. From the channel the conveyer passes over a roller 30, and then through channels 28, 31, 32, 33 having apertures 34 discharging to the station. The gap between channels 26, 28 permits adjustment of the conveyer length. The conveyer returns to the pipe over a drum 35 which is carried by a spring to prevent stretching of the conveyer as the pipe is driven. A trough may extend through the pipe under the lower run of the conveyer. In installations in which the working face is removed manually the leading end of the conveyer is covered.

Abstract: 1,230,481. Regulating I.C. engines. ALFA ROMEO S.p.A. June 10, 1968 [June 10, 1967; April 6, 1968], No.27571/68. Heading F1B. A regulation for an I.C. engine fuel injection pump comprises a three-dimensional cam displaceable in one direction according to engine speed and in another direction according to throttle position or air intake manifold pressure, a cam follower rockable on a pivot axis by operation of the cam, a correcting device arranged to modify the action of the follower on a control for varying the pump output, the device comprising an auxiliary lever on a pivot, a projection at one end of the auxiliary lever remote from the lever axis arranged in an angle formed between the edge of a member rocked by the follower and an edge of a second lever which is rockable on a fixed axis and is operatively connected to the pump control, the projection contacting the edges, and meons for displacing the pivot of the auxiliary lever by an amount related to the difference between the actual and normal engine temperatures so as to cause the projection to vary the angle between the edges and thereby increase the pump output when the engine is cold. The three-dimensional cam 1, Fig.1, is rotatable by a lever 6 in accordance with the throttle position and is movable axially by a centrifugal governor 3 driven by the camshaft 4. The cam 1 operates a follower in the form of a bell crank 10, 12, movement of the bell crank about its pivot 11 being transmitted through a peg 13 to a lever 14, also pivoted at 11. The lever 14 is connected through a link 15 to the control rack 16 of the pump. The peg 13 is carried by an auxiliary lever 18 whose pivot 19 is carried by a lever 20, Fig.3, pivoted at 21. When the engine temperature is below its normal value, the lever 20 is turned in an anticlockwise direction by a manual control or a thermostat 28 so that the pivot 19 is brought from the position seen in Fig.1 to the position seen in Fig.3, in which it is below the pivot 11. Consequently, the peg 13 moves the lever 14 clockwise relative to the bell crank 10, 12 to adjust the rack 16 to increase the fuel output. When the engine is started, a solenoid 34 turns the bell crank 30 about a pivot 31 so that a peg 29 turns the auxiliary lever 18 to adjust the rack 16 to increase the fuel output to facilitate starting. There is some lost motion before the peg 29 contacts the auxiliary lever 18, the auxiliary lever being shaped so that the lost motion increases as the pivot 19 is raised towards the normal-temperature position, whereby the increase of fuel output for starting is diminished.

Abstract: 1335441 Regulating fuel SEA BIRD (CLEAN AIR FUEL SYSTEMS) Ltd 6 Jan 1971 650/71 Addition to 1192275 Heading F1B A fuel control valve 50 is controlled by a flexible diaphragm 7 responsive to the pressure difference at a Venturi adapted for connection to an engine exhaust pipe, the fuel supply increasing as the suction increases. An adjustable screw 53 limits movement of valve 50, which is also controlled by a diaphragm 3 responsive to the pressure difference at a Venturi in the air inlet pipe. Suction here also controls a supply port 28 by means of diaphragm 3A and lever 26. At constant engine speed, an increase of load increases exhaust temperature increasing the pressure difference at the exhaust Venturi and opening valve 50. If the engine speed increases, the increased gas flow in inlet and exhaust Venturis produces, by means of diaphragms 3 and 7, equal and opposite forces on rod 248 so valve 50 remains steady and fuel supply is increased by opening of port 28 by diaphragm 3A. If the fuel injectors stick open so that exhaust gas temperature rises, diaphragm 7 will urge rod 24B to the left but there will be no effect on port 26 sothe gas flow will remain the same if the valve 50 is already in contact with screw 53.
